Specification o'f Letters Patent.

Application led August 19, 1 918. Serial No. 250,594.

To all'whom it may concern Be it known that I, HERBERT W. CHRIS- TIAN, a citizen of the United' States of America, residingiat Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Combined Water Heaters and Drippers, of which the following is a specisim le, durable and easily regulated device of t e above character that may be operated from an ordinary ,electric lighting system, either of one hundred and ten or two hundred and twenty volts, the device being provided with a switch that not only serves its usual purpose, 'butpermits of the-heating element being manua ly regulated to perform predetermined work.

The device will be hereinafter described and then claimed and reference will now be had to the drawing, wherein- Figure 1 is a front elevation of the com-v bined water heater and dripper;

"Fig, 2 is a vertical sectional view of the j same' 3 is a horizontal sectional view taken on the line III-III of Fig. 2;

4 is a similar view taken on the line IV'-IV of Fig. 2;

V- of Fig. 2; i

Fig. 6 is an enlarged vertical sectional view of a thermostat adapted to form part of the device;

Fig. 7 is a horizontal sectional view of the thermostat taken on the line VII-VII of Fig. 6,- and Fi 8 is a diagrammatic view illustratin t e electrical connections of the device.

n the drawin the reference numeral l denotes a cylindiical or tubular metallic body 1 provided with spaced partitionsv 2 and 3, said partitions being set in vfrom the Fi 5 is a. similar view taken on the line ends of the body and soldered or otherwise secured thereto so as to be practically integral with said body. The ends of the body are interiorly screwthreaded, as at 4, and said body is provided with apertured ears -5 and a bracket 6, 'the former permitting of the body being suspended from a suitable support, and the latter permitting of said body being rigidly securedA to a support.

7 denotes a main reservoir, preferably in the form of a glass tube having its ends exteriorly screwthreaded, so'that one end of the main reservoir may be screwed into the upper end of the body 1 and the opposite end of said reservoir provided with a detachable cap 8. Gaskets 9 are used at both ends of the main reservoir 7 and after said reservoir is screwed into the upper end of the body 1, cement or other material may be employed for fixing the main reservoir relative to the body 1 to avoid any leakage betweenthe lower end of the main reservoir and the upper end of the body 1. By removing the cap 8, the main reservoir may be easily filled.

10 denotes an auxiliary reservoirhaving its ends exteriorly ls crewthreaded and one end thereof'mounted in the lower end of the. body 1 and the opposite end thereof provided with'a closure cap 11. Cement or other material is also used to fix the ends of the auxiliary reservoir 10 so as to avoid leakage and gaskets 12 will contribute to i this result.

13 denotes a pipe axially of the tubular body 1 establishing communication between the reservoirs7 and v10, said pipe being suitably held by the partitions 2 and 3 with the lower end of the pipe vextending into the l auxiliary reservoir and reduced to form a nipple 14, which may be closed by a valve 15 on a float or buoyant body 16 located within the auxiliary reservoir 10. The valve 15 and its supporting oat constitute automatic means for preventing the auxiliary reservoir 10 from being flooded by the contents of the main reservoir 7.

17 denotes a valve carried b the pi e 13, saidvalve being preferably o the nee le type so that the same may be minutely regulated b a valve stein 18,extendin out of the bo y 1. By adjusting the va ve stem 18 the contents of the main reservoir 7 may enter the auxiliary reservoir 10, drop by drop, and thus provide an intermediate feed between the main and auxiliary reservoirs'` 19 denotes a partition within the lower end of the auxiliary reservoir 10 and in spaced relation to the bottom gasket or washer 12, said partition having a series of openings to coperate with the partition 3 -in the body 1 in supporting a thermometer 20, electric heating elements 2l, 'and a thermostat 22; the float or buoyant body 16 being recessed or cut away to provide clearance for the elements 20 to 22 inclusive which are disposed longitudinally of thev to the partitions 3 and 19 by peripheral flanges 4. In the lower end of the tube 22 is located an insulator 25 `and connected to said insulator by screws 26 or other fastening means are arms 27 and 28, the former being made of materials susceptible to expansion and contraction by the temperature of the water in the auxiliary reservoir 10, and the latter is resilient in order that it may be adjusted by a. set screw 29 adjustable at the upper end of the tube 22 and extending through the ltubular bodyl. The ends of the arms 27 and 28 are in proximity to each other and are adapted to normally contact, said arms being in an electriccircuit as will hereinafter appear. The arms protrude out of the upper end of the tube 22 and may be observed through an opening 30 inthe tubular body 1 of the device.

The electric heating elements 21 are two in number, each comprlsing a suitable casing having coils 31, 32 therein suitably insulated from each other, as at 33. The coils of one heating element are adapted for currents of one hundred and ten volts and the coils of the other heating element for a current of two hundred and 'twenty volts, but it is possible to dispose the coils so that both heating elements may be placed in a circuit of one hundred and ten volts or a circuit of two hundred and twenty volts. To accomplish this, a novel switch `34 is employed, said switch being in the form of an oblong cylindrical` casing containing contacts 40 to 43 inclusive adapted to be engaged by ascontact member 44 slidable on a rod 45 and operatable from 4the exterior of the switch casing. Cables may extend into and through the switch casing to carry the necessary wires or conductors for the heating elements 21, the thermostat 22, and an electric light socket4 46 which permits of the combined device being connected to and operated from an ordinary electric lighting circuit.

By reference to Fig. 8, it will be noted that the coil 31 and the thermostat 22 are adapted to be connected by wires 47 to a suitable source of electrical energy, and then the thermostat 22 is connected by a wire 48 to the rod 45, while the coil 31 is connectedby a wire 49 to the contact 40. With the thermostat 22 normally closed, there is an electric circuit. through the coil 31 for an initial heat in the auxiliary reservoir. By shifting the contact member 44 to bridge the contacts 40 and 41, the coil 32 is brought into circuit through the medium of the wires 50 and 5l. This may be for a current of one hundred and ten volts and should it be desired to operate the other electric heating element in connection with a current of two hundred'and twenty volts the contact member 44 is shifted to the contact 42 or to bridge said contact with the contact 43, when simila-r circuits will be established as in connection with the heating element previously mentioned.

From the foregoing, it vwillbe observed that either or both of the heating elements may be utilized, according to the electrical connections, for heating the water or liquid admitted to the auxiliary reservoir 10 from the main reservoir 7, and by regulating the thermostat 2, it is possible to have the contents of the auxiliary reservoir l0 heated to a predetermined temperature and then the electric current automatically cut oii' until the temperature ofthe contents of the reservoir is lowered to a predetermined point, when an electric circuit will again be automatically established to heat the water or solution within the auxiliary reservoir.

Any suitable provision may be made, as at 52, for removing the contents of the auxiliary reservoir 10. A. conventional form of pet cock has `been shown so as to permit ofthe contents of the reservoir being removed drop by drop or in a very small stream.

It is thought that the operation and utility of the device will be apparent without further description, and while in thevdrawing there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is :f-

A combined-water heater and dripper comprising a body, a main reservoir connected to the upper end thereof, an auxiliary reservoir, connected to the lower end of said body, means in said body establishing communication between said main reservoir and said auxiliary reservoir, electric heating elements in said auxiliary reservoir, and means in said body adapted to regulate the operation of said electrical elements,
